South Korea said Monday that two South Korean tour guides were killed and nine others were injured as a bomb tore through their bus in Egypt. Still, 31 people from a same church in South Korea all survived the attack on Sunday, the foreign ministry said. Their church also confirmed the 31 people survived the bombing, though some of them are injured.

The bus was carrying a total of 35 people — 31 people from a same church, two South Korean guides, an Egyptian guide and an Egyptian driver — when an explosion occurred at Taba border crossing with Israel in south Sinai.

South Korea also held an emergency meeting at the foreign ministry at around 1 a.m. to try to assess the situation as it dispatched three officials in Egypt and Israel to the site of the accident.

Foreign Ministry spokesman Cho Tae-young said South Korea is in talks with the Egyptian authorities.

Another foreign ministry official said it was not clear whether South Koreans were targeted in the explosion.
